Filed: 1919-07-25
Abstract: 151,770. Morgan, E. H. July 25, 1919, Mechanical stoking; doors; furnace fronts; grates.-In an underfed furnace of the kind described in Specification 11736/15, sagging of the inner end of the fire-supporting blade is prevented by causing the blade and the door with which it engages to be tilted when the door and blade are raised to supply fuel to the grate. The blade j, Fig. 3, is inserted through the opening h<6>, Fig. 1, in the door and beneath the fire, the lugs j<1> on the blade engaging with recesses h<5> in the door h, and by means of a pedal and ropes attached to lugs h<3> on the door, the door and blade are raised. Tilting of the door and blade is effected during their upward movement by the upper part of the door engaging with an inclined surface a<2> on the furnace front, and the lugs h<3> engaging with inclined surfaces i<2> on the supports for the pulleys over which pass the ropes of the lifting gear. Inclined surfaces h<1>, h<2> on the door and a rod i<1> serve to guide the door. To facilitate the insertion of the blade j. fuel trough l and rammer m, Fig. 7, they arc connected by ropes k passing over pulleys k<1> to balance weights k<4> and suspended from an overhead rope or track k<2> which may be arranged to travel transversely in front of two or more furnaces. An air-tight joint which permits expansion is formed between the furnace front and flue by an expanding part-ring b which is screwed to the flange a<1> on the furnace front, the holes in the ring being slotted as shown. The grate is supported at its front and rear ends by uprights which rest on adjustable cross bearers comprising a foot-piece c, an upper piece d with lugs d<2> against which the uprights abut, and a packing-piece f, secured together by a bolt e, the hole in the foot-piece being slotted to allow for adjustment.

Abstract: 1,186,346. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 9 May, 1967 [27 April, 1966], No. 18533/66. Heading G6C. A fuel element comprises a cluster of parallel, spaced fuel rods secured at one end to a support grid bearing the weight of the fuel rods, the securing of the fuel rods to the support grid being releasably effected by the deformation of a part of the support grid into engagement with an end portion of each fuel rod, whereby the fuel rods are restrained against axial movement relative to the support grid. In the embodiment shown in Fig. 2, a top support grid 18 has each of its cells 19 formed with an inturned continuous annular lip 21 at its lower end and eight hook-shaped tabs 22 separated by dots 23 at its upper end. Initially, the internal diameter measured across the outer edges of the tabs 22 is not less than that of the cylindrical portion 20 of the cell 19. Each fuel rod 24 has a tubular sheath 25 with circumferential or helical external fins 26, and an upper end portion 27 of enlarged diameter which terminates short of the extreme upper edge of the sheath 25. Interposed between the end cap 30 and the top fuel pellet 29 is a heat-insulating pellet 31 (e.g. alumina). The fuel rod 24 is fitted to the grid 18 from above and is moved downwardly until the lip 21 engages the shoulder 28 formed by the lower edge of the upper end portion 27. The tabs 22 are then deformed inwardly so that their upper edges meet circumferentially and enclose and contact the welded upper end 32 of the fuel rod, thereby preventing any significant upward axial movement of the fuel rod relative to the support grid.

[Also in Division F1] A propeller or helicopter rotor comprises a continuous sinuous working surface disposed about the axis of rotation and having a changing axial section shape and ridge and valley regions, each axial section of the working surface curving smoothly throughout its full extent in the direction of general flow and generally conforming to a sine-like curve which undulates smoothly in the direction of general flow, each successive axial section occupying a slightly advanced position on its sine-like curve from the position of the preceding axial section on its sine-like curve, and the change in curvature of the working surface along all paths of actual flow over the working surface occurring at a rate resulting in a smoothly undulating flow pattern being imparted to the fluid and the direction of undulation smoothly reversing through the ridge and valley regions. Fig. 2 shows a marine or aerial propeller or a helicopter rotor comprising a single annular blade 10 attached to a hub 12 by two arms 14 which, as shown, may curve rearwardly slightly from their inner to their outer ends. In cross-sections taken at right angles to the axis X of rotation, the blade 10 comprises several complete waves, e.g. two as shown, which may be sine waves generated from a circular axis Y of generation. The cross-sections change progressively in angular disposition from the leading edge of the blade to the trailing edge along a helical path but remain of substantially the same configuration. Both the inner and outer surfaces of the blade 10 form working surfaces. An under water vessel V, Fig. 16, comprises a rotating propeller R3<SP>1</SP> interposed between non-rotating sections 18, 20. The rotor is in this ease of solid form with an outer working surface formed as described above.
